-This invention relates to attachments for telephones, and has for oneof its objects to provide. :means for supportingl tlie receiver,

ployed lfor vholding the receiver to the ear.

Another object Ais to provide an attachment of this kind on which thereceiver may be nicely adjusted to exactly register with the 'ear of theuser when talking into the mouth piece. A `further object is to prov-ideimproved v.means f for retaining the receiverysupporting armin either ofits positions,

that is, when n'ot in use, aswell as whenin use.. Further objectswillappearas the description proceeds',

' The invention will be `first hereinafter described inv connection withthe accompanyspecification, and. then more sfpecically ldefined in theclaims .at the end vof' the description.

In the accompanying drawings, wherein similar referencecharacters areused to designate 'corresponding' parts throughout the several views:

Figure 1 is a perspective view of a desk telephone showing my improvedattachment applied thereto, the receiver-supporting arm being shown inthe position it occupies when the :telephone is not in use. Figure 2 isa fragmentary side View of the telephone and attachment showing thereceiver-supporting larm in position for use in .solid li'nes, and inthe position it occupies when not in use in dotted lines, thecorrespondingpositions of the receiver hookl of the telephone being alsoindicated. Y

Figure 3 is a detailed side view of the outer end of the bracket off theattachment, showing the receiver-supporting arm back in idle position. l

Figure 4 is a part of the ball clamp at the free end of thereceiver-'supporting arm, and c Figure 5 is a detailed perspectiveviewjof the clamp for securing the bracket to the standard of thetelephone.

In `Figures 1 and2, an ordinary desk telephone is show-n with the vusualstandard v1, mouth piece 2, receiver 3, and receiver-'supporting hook 4.The receiver isj attached to isr fastened around the standard 1 ofthedetailed perspective' view of 1927. serial No.;.17.'a,729.,`

ltelephone just below the. hook 1 bymeansof a clamp` 8. As illustratedin Figure 5. said clamp 8 yconsists 'of ysupplemental semi-circularmembers 9 and 10, one of which may be Y integral with the bracket 7,whileihe other is preferably detachably secured thereto by a` screw orbolt 1 1. The free ends of the members 9 Aand 1 0 ofthe clamp `areinterlocked at 12, preferabl by" 'the dove-tail or T-connection shown',w ich `unitessaidouter ends of the members when their inner ,endportions are connected by the screw llmbut which permits the separablemember 10 to be entirely removed when-'saidv screw l11 is l taken out inorder to permit the ready application of the clamp about the standard ofa telephone;

In ordery to permit the receiver to be ladjustedl so as to properly`register with `the ear of different userswhenthey are speaking into themouth piece of' the telephone, the arm 5 is provided with atelescopiceX- tension 13 which `may bel sethat different lengths by aclampingscrew 14, and a ball 15 is formed at `the extremity'of saidexten-y sion arm-13 to tit in a clamp 16 to which the receiver is'secured.. SaidV ball clamp 16, as shown in Figures 1 and 4, comprisessupplemental -jaw members 17 and 18 having a concave portion at one endto engage vthe ball 15, while their other lends are spaced apart by anangu'larly` bent portion 19 on one Vj aw interlocking with the `otherjaw by means of a tongue 2Q onpsaid part 19 vfitting in a notch 21 inthe jaw 18. Said interlocking connection between the jaws retainsI themin properalignment when they are clamped together about the ball 15.bymeans of `set screw 22 which passes through the jaw `18 and engages asocket 23 in the Shanks 214: of the receiver clamp .25, which shanks aresecured to the inner face of the jaw 17 of the ball clamp vby.screvv s26, Figure 4.v g

.The receiver may be further adjustedby meansvof a set-screw 27 on aprojecting lug 28 at the pivoted'end ofthe arm 5, saidset screw beingadaptedto engage a stop |29 eX- tending into the rbifu'rcated endportion 30 of thebent .portion 6 kof the bracket, so that by adjustingsaid set screw the forward swing of 'the receiver-supporting arm maybearrested at different points. The Vset sc -rew 27 may Vbe fixed inadjusted position by a' locking screw 31. It will thus be seen 32 whichserves as pivot for the `arm 5, is a j lever 33 which extends alongsaidv bent portion 6 of the bracket and has its end passed through theloops 34'atthe end of the re'-A ceiver hook i ofthe telephone. At theother side `of its pivot the leverl 33 has a bent tongue 35 extendinginto the path of the lug 28 on Vthe arm '5. The arrangement 0f saidlever, tongue, and lug is such that .when the arm- 5, which supports thereceiver,

is swung backward, as shown in Figure 1, and in dotted lines in Figure2, the lug 28 engages the tongue 35 and moves the lever 33 and receiverhook 4 downward to cut oil' the circuit to the telephone, as is usuallydone when the receiver is placed on said hook. Y

To insure the proper retention of the r`e ceiver-supporting arm in. itsrearward or idle .position for maintaining the telephone circuitnormally broken, a coiled spring 36 is fastened at one endto the bentportion 6 of the bracket at 37, and at the other end to a bent lug 38`on the pivot hub 39 of the arm 5, the arrangement of said lug 38 beingsuch that it will'- be positioned at one side of the pivot 32 of saidarm when the latter is swung backward to its idle position, Yas shown inFigures 1 and` 3, and in dotted lines in Figure 2. When the arm 5 isyswung forward, as shown in solid lines in Figure; 2, the lug 38 isbrought to a position at the other side of the pivot 32, so that thespring 36 then serves to hold the arm in position to support'thereceiver in line with the ear of the user. It will be noted that thespring 36 will move the arm 5 in either direction after the latter hasbeen manually swung far enough to bring the lug 38 past the line 0f theivot 32 and point of connection 37 of the inner end of said spring. Thisinsures the proper movement of the arm V5 rearward to its fullest extentfor cutting off the telephone circuit, even though said arm is notpushed all the way back manually. Obviously, the arrangement of theAspring 36 will also insure the movement of 'the re ceiver-supporting armto the limit of its forward movement for bringing the receiver intoproper register with the ear of the user, and will hold said arm in thatposition while the instrument is being used.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is z- 1.
